Description

本発明は電動工具に設けられた照明ライトの改良技術に関する。   The present invention relates to a technique for improving an illumination light provided in a power tool.

従来から、暗い場所での作業を容易に行うために、作業対象箇所を照らす照明ライトを備えた電動工具が知られており、この電動工具においては、例えばインパクトドライバの場合は、ハンマケースの直近に配置されているものもあるが、制御基板を備えたインパクトドライバにおいては、多くは制御基板をバッテリの上面部に配置している。このため、コストや組み付け性の点からはライトを制御基板上に置く方が好ましい。   Conventionally, in order to easily perform work in a dark place, an electric tool having an illumination light for illuminating a work place is known. In the case of an impact driver, for example, in the case of an impact driver, a power tool is provided. However, in many impact drivers equipped with a control board, the control board is arranged on the upper surface of the battery. For this reason, it is preferable to place the light on the control board from the viewpoint of cost and assembly.

ところで、上記の照明ライト取付け位置では、ドライバビットのような先端工具によって作業するための作業部位に対する照射範囲が大きくなってしまう。つまり、照明ライトを工具本体の先端の、先端工具の近傍に配置する場合は、照明ライトの照射方向は、先端工具の軸の延長上にすればよいので、照射範囲を一定範囲に絞ることができる。しかし、電源バッテリは工具本体の下部のグリップ部のさらにその下端に取り付けられているから、その上面部の制御基板上に照明ライトを取付けるときは、先端工具の軸の横から照射するような状態になる。このため、例えば短いビットや短いネジを使用する場合の作業部位は照明ライトの位置から近いが、長いビットや長いネジを使用する場合の作業部位は照明ライトの位置から遠くなる。したがって、２つの作業部位を同時に照射するためには、照射範囲を広くする必要がある。しかし、照射範囲を単純に広げると、照射された部分は大きな円になるので、不要な部分まで照らす無駄があるとともに、照明ライトの照射方向は作業部位から近くも遠くもない半端な位置に向けなければならないから、遠い作業部位は暗くなってしまい、必要な作業対象箇所で十分な明るさが得られない。   By the way, in the above-mentioned illumination light mounting position, the irradiation range with respect to the work site | part for working with a front-end tool like a driver bit will become large. In other words, when the illumination light is arranged near the tip tool at the tip of the tool body, the irradiation direction of the illumination light only needs to be on the extension of the axis of the tip tool. it can. However, since the power supply battery is attached to the lower end of the grip part at the bottom of the tool body, when installing the illumination light on the control board on the upper surface, it irradiates from the side of the tip tool axis. become. For this reason, for example, the work site when using a short bit or a short screw is close to the position of the illumination light, but the work site when using a long bit or a long screw is far from the position of the illumination light. Therefore, in order to irradiate two work parts simultaneously, it is necessary to widen the irradiation range. However, if the irradiation range is simply expanded, the irradiated part becomes a large circle, so there is a waste of illuminating unnecessary parts, and the irradiation direction of the illumination light is directed to an odd position that is neither near nor far from the work site. Therefore, a distant work part becomes dark, and sufficient brightness cannot be obtained at a necessary work target part.

そこで、このような無駄を省き、必要な部分だけを集中して照射するため、照明ライトの角度を、作業対象箇所の距離に従って、遠い部位と近い部位に応じて手動で切り替えるものも知られている（特許文献１、２参照）。これによれば、ビットやネジの長短などに合わせて角度を切り替えるだけであり、照射範囲を広くする必要がないので、作業対象箇所が暗くなってしまうという問題はない。
特開２００３−２４５８７５ 特開２００３−２１１３７４ Therefore, in order to eliminate such waste and concentrate and irradiate only the necessary part, it is also known that the angle of the illumination light is manually switched according to the distance to the work site according to the distance to the work site. (See Patent Documents 1 and 2). According to this, only the angle is switched according to the length of the bit or screw, and there is no need to widen the irradiation range, so there is no problem that the work target portion becomes dark.
JP2003-245875 JP2003-2111374

しかしながら、ビットや釘の種類に応じてライトの角度を変えるということになると、作業に合わせてその都度作業者が手で角度を調整する必要があり、取り扱いが面倒で操作性に問題があった。   However, when the angle of the light is changed according to the type of bit or nail, the operator needs to adjust the angle by hand each time according to the work, and handling is troublesome and there is a problem in operability. .

本発明は、上述の問題点を解消し、照明ライトによる照射範囲を縦長にすることにより、作業対象箇所の必要な範囲を、遠い部位も近い部位も同時に明るく照射することができるライト付き電動工具を提供することをその課題とする。   The present invention eliminates the above-mentioned problems and makes the irradiation range by the illumination light vertically long so that the necessary range of the work target location can be illuminated brightly at the same time in both the far and near parts simultaneously. The issue is to provide

上記課題を解決するため、本発明の請求項１に係る発明は、駆動用モータと回転駆動伝達部と先端工具取付部とを備えた工具本体と、該工具本体の下方に設けられたグリップと、該グリップの下部に設けられた電源バッテリの取付部とを備えるとともに、上記電源バッテリの取付部に上記先端工具による作業部位を照射する照明ライトを設けたライト付き電動工具において、上記照明ライトを、その取付位置から近い作業部位を照射する発光手段と、遠い作業部位を照射する第２の発光手段とによって構成し、第１の発光手段と第２の発光手段とは同じ位置の左右に同じ角度で設けられ、発光手段の前部に設けられた透明なカバーの、上記各発光手段に対応する部位の屈折角を変えて近い作業部位と遠い作業部位を同時に照らすことを特徴とする。 In order to solve the above-mentioned problems, an invention according to claim 1 of the present invention includes a tool body including a drive motor, a rotational drive transmission portion, and a tip tool mounting portion, and a grip provided below the tool body A power battery mounting portion provided at a lower portion of the grip, and a power tool with a light provided with an illumination light for irradiating a work site by the tip tool on the power battery mounting portion. The light emitting means for irradiating the work site close to the mounting position and the second light emitting means for irradiating the work site far from the mounting position, the first light emitting means and the second light emitting means are the same on the left and right at the same position. provided at an angle, and wherein the illuminating transparent cover provided in front of the light emitting means, work site close by changing the refraction angle of the portion corresponding to the respective light emitting means and the distant work site at the same time That.

請求項２に係る発明は、請求項１において、上記２個の発光手段のうち、遠い作業部位を照らす発光手段に対応する一方の発光手段に対応する部位の透明カバーの前端には、上記発光手段から発光された照射光を絞るレンズ部を形成し、近い作業部位に対する照射角度を、遠い作業部位に対する照射角度よりも大きくしたことを特徴とする。 The invention according to claim 2 is the light emitting device according to claim 1, wherein the light emitting device is arranged at the front end of the transparent cover of the portion corresponding to one of the two light emitting devices corresponding to the light emitting device that illuminates a distant work site. A lens portion for narrowing the irradiation light emitted from the means is formed, and the irradiation angle for the near work site is made larger than the irradiation angle for the far work site .

請求項３に係る発明は、請求項１において、上記照明ライトを、２個の発光手段に代えて、１個の発光手段とし、この発光手段の前方に設けた透明カバーの一部の屈折角を変えて近い作業部位と遠い作業部位を同時に照らすことを特徴とする。   According to a third aspect of the present invention, in the first aspect, the illuminating light is replaced with two light-emitting means, and is a single light-emitting means, and a refraction angle of a part of the transparent cover provided in front of the light-emitting means. It is characterized by illuminating near and far working parts at the same time.

請求項４に係る発明は、請求項３において、上記透明カバーの遠い作業部位を同時に照らす方の部分には、上記発光手段から発光された照射光を絞るレンズ部を形成し、近い作業部位に対する照射角度を、遠い作業部位に対する照射角度よりも大きくしたことを特徴とする。 According to a fourth aspect of the present invention, in the third aspect of the present invention, a lens portion that squeezes the irradiation light emitted from the light emitting means is formed on the portion of the transparent cover that simultaneously illuminates the distant work site, and the near work site is The irradiation angle is made larger than the irradiation angle with respect to a distant work site .

請求項１に係る発明によれば、照明ライトを、その取付位置から近い作業部位を照射する発光手段と、遠い作業部位を照射する第２の発光手段とによって構成し、第１の発光手段と第２の発光手段とを同じ位置に設けるとともに、近い作業部位と遠い作業部位とを同時に照射させる構成により、遠い部位も近い部位も同時に明るく照射することができ、ビットやネジの長短などに合わせて照明ライトの角度を切り替えるという面倒な操作が必要ない。また、１箇所に集中的に配置したから組立ても容易である。したがって、取り扱いが簡単で、組立性、作業性が向上する。   According to the first aspect of the present invention, the illumination light is configured by the light emitting means for irradiating the work site close to the mounting position and the second light emitting means for irradiating the far work site, and the first light emitting means The second light-emitting means is provided at the same position, and the structure that irradiates the near work site and the far work site at the same time can irradiate the far site and the near site at the same time. This eliminates the troublesome operation of switching the angle of the illumination light. In addition, it is easy to assemble because it is concentrated in one place. Therefore, handling is easy, and assemblability and workability are improved.

また、上記２個の発光手段は左右に同じ角度で設けられ、発光手段の前部に設けられた透明なカバーは、上記各発光手段に対応する部位の屈折角を変えて近い作業部位と遠い作業部位を同時に照らす構成であるから、２個の発光手段の取り付けが楽であり、取り付けスペースも小さくて済む。 Further, the two light emitting means are provided at the same angle on the left and right, and the transparent cover provided at the front of the light emitting means changes the refraction angle of the part corresponding to each of the light emitting means and is far from the near working part. Since it is the structure which illuminates a work site | part simultaneously, the attachment of two light emission means is easy, and an installation space may be small.

請求項２に係る発明によれば、上記２個の発光手段のうち、遠い作業部位を照らす発光手段に対応する一方の発光手段に対応する部位の透明カバーの前端には、上記発光手段から発光された照射光を絞るレンズ部を形成したので、遠い作業部位を照らす光は拡散せずに必要な作業部位を明るく照射することができる。 According to the second aspect of the present invention, light is emitted from the light emitting means at the front end of the transparent cover of the portion corresponding to one of the two light emitting means corresponding to the light emitting means for illuminating a distant work site. Since the lens portion for narrowing the irradiated light is formed, the light for illuminating the distant work site can be brightly illuminated without diffusing the light.

請求項３に係る発明によれば、上記照明ライトを１個の発光手段とし、この発光手段の前方に設けた透明カバーの一部の屈折角を変えて近い作業部位と遠い作業部位を同時に照らすようにしたから、１個の発光手段でも照射範囲を縦長にして、作業対象箇所の必要な範囲を、遠い部位も近い部位も同時に明るく照射することができる。 According to the third aspect of the present invention, the illumination light is used as one light-emitting means, and a near working part and a far working part are simultaneously illuminated by changing the refraction angle of a part of the transparent cover provided in front of the light-emitting means. Thus, even with a single light emitting means, the irradiation range can be made vertically long, and the necessary range of the work target location can be simultaneously illuminated brightly at both the far site and the near site.

請求項４に係る発明によれば、さらに、透明カバーの遠い作業部位を同時に照らす方の部分には、上記発光手段から発光された照射光を絞るレンズ部を形成し、近い作業部位に対する照射角度を、遠い作業部位に対する照射角度よりも大きくしたから、遠い作業部位を照らす光は拡散せず、その照射角度βは、上記角度αよりも小さくなるので、必要な作業部位を明るく照射することができる。作業対象箇所の必要な範囲を、遠い作業部位Ｂも近い作業部位Ａも同時に明るく照射することができる。 According to the fourth aspect of the present invention, a lens portion for narrowing the irradiation light emitted from the light emitting means is formed on the portion of the transparent cover that simultaneously illuminates the far working site, and the irradiation angle with respect to the near working site. Is larger than the irradiation angle for the distant work site, the light illuminating the distant work site is not diffused, and the irradiation angle β is smaller than the angle α, so that the necessary work site can be illuminated brightly. it can. The necessary work area can be illuminated brightly at the same time in both the far work site B and the close work site A.

図１（ａ）（ｂ）は、それぞれ本発明に係る電動インパクトドライバの側面図を示す。電動インパクトドライバは、図示しないが、工具本体１の後部に電動モータを収納し、前部に回転駆動部と駆動伝達部を介してドライバビット（先端工具）２ａ又は２ｂを回転自在に設けたもので、回転駆動部にはドライバビット２を回転させるとともに連続的に打撃する機構が設けられている。また、工具本体１の下部にはグリップ部３が設けられ、さらにグリップ部３の下部には電源バッテリの取付ベース４が形成され、該取付ベース４には電源バッテリ５が着脱自在に設けられている。   1A and 1B are side views of an electric impact driver according to the present invention, respectively. The electric impact driver is not shown, but an electric motor is housed in the rear part of the tool body 1, and a driver bit (tip tool) 2a or 2b is rotatably provided in the front part via a rotation drive part and a drive transmission part. Thus, the rotation driving unit is provided with a mechanism for rotating the driver bit 2 and continuously hitting it. A grip portion 3 is provided at the lower portion of the tool body 1, and a power supply battery mounting base 4 is formed at the lower portion of the grip portion 3. A power source battery 5 is detachably provided on the mounting base 4. Yes.

グリップ部３の上端部には起動用トリガレバー６が設けられ、また図示しないスイッチにより、トリガレバー６の操作によりモータが駆動しているときは照明ライト７が点灯されるように構成されている。   An activation trigger lever 6 is provided at the upper end of the grip portion 3, and the illumination light 7 is turned on by a switch (not shown) when the motor is driven by the operation of the trigger lever 6. .

上記照明ライト７は電源バッテリ５の取付ベース４に設けられた制御基板８（図２（ａ）（ｂ）、図３参照）の上部に設けられている。照明ライト７は２個の発光ダイオード（発光手段）７ａ、７ｂによって構成され、これらの２個の発光ダイオード７ａ、７ｂのうち、一方の第１の発光ダイオード７ａは、その取付位置から短いドライバビット（又は釘）２ａを使用した場合等に必要な近い作業部位Ａを照らす方の発光手段であり、他方の第２の発光ダイオード７ｂは、長いドライバビット（又は釘）２ｂを使用した場合等に必要な遠い作業部位Ｂを照らす方の発光手段であるが、発光ダイオードとしては同じ高輝度発光のものが使用されている。   The illumination light 7 is provided on an upper portion of a control board 8 (see FIGS. 2A and 2B and FIG. 3) provided on the mounting base 4 of the power battery 5. The illumination light 7 is composed of two light emitting diodes (light emitting means) 7a and 7b, and one of the two light emitting diodes 7a and 7b has a short driver bit from the mounting position. (Or nail) 2a is a light emitting means for illuminating a nearby work site A required when the 2a is used, and the other second light emitting diode 7b is used when a long driver bit (or nail) 2b is used. The light emitting means illuminates the necessary distant work site B, and the light emitting diodes having the same high luminance are used.

上記第１の発光ダイオード７ａと第２の発光ダイオード７ｂは、制御基板８に固定された一体のケース（カバー兼用）１１の左右に同じ角度で同じ方向を照射するように収納されている。つまり、上記ケース１１は制御基板８の上面に一定の角度で取りつけられ、通常の場合には第１と第２の発光ダイオード７ａ、７ｂが、主に近い作業部位を照射するように取り付けられている。   The first light-emitting diode 7 a and the second light-emitting diode 7 b are accommodated so as to irradiate the same direction at the same angle on the left and right of an integrated case (also used as a cover) 11 fixed to the control board 8. In other words, the case 11 is attached to the upper surface of the control board 8 at a fixed angle, and in the normal case, the first and second light emitting diodes 7a and 7b are attached so as to irradiate mainly close work sites. Yes.

次に、図３及び図４（ａ）（ｂ）に示されるように、第１と第２の発光ダイオード７ａ、７ｂの前部には、ガラス又は透明な合成樹脂から構成されたカバー１１が取り付けられ、第１と第２の発光ダイオード７ａ、７ｂから出た光は上記カバー１１を通過して外部に照射するようになっている。上記カバー１１は上記第１と第２の発光ダイオード７ａ、７ｂに対応する部位においてそれぞれから出た光の屈折角を変えるようになっている。すなわち、第１の発光ダイオード７ａに対応する部位ではカバー部１１ａの厚さは均一になっているが、第２の発光ダイオード７ｂに対応する部位ではカバー部１１ｂの厚さは、図の上側（近い作業部位に対応する側）よりも、図の下側（遠い作業部位に対応する側）の方が肉厚になっている。これにより、第２の発光ダイオード７ｂから出た光はカバー部１１ｂを通過したときに中心軸が角度θだけ屈折し、そのプリズム効果によって第２の発光ダイオード７ｂの照射方向が遠い作業部位を向くようになっている。   Next, as shown in FIG. 3 and FIGS. 4A and 4B, a cover 11 made of glass or transparent synthetic resin is provided at the front of the first and second light emitting diodes 7a and 7b. The light emitted from the first and second light emitting diodes 7a and 7b is attached to the outside through the cover 11. The cover 11 changes the refraction angle of light emitted from each of the portions corresponding to the first and second light emitting diodes 7a and 7b. That is, the thickness of the cover portion 11a is uniform at the portion corresponding to the first light emitting diode 7a, but the thickness of the cover portion 11b at the portion corresponding to the second light emitting diode 7b is the upper side of FIG. The lower side of the figure (the side corresponding to the far working site) is thicker than the side corresponding to the near working site. Thereby, when the light emitted from the second light emitting diode 7b passes through the cover portion 11b, the central axis is refracted by an angle θ, and the prism effect causes the irradiation direction of the second light emitting diode 7b to be directed to a work site far away. It is like that.

上記構成によれば、発光ダイオードの前部に設けられた透明なカバー部１１ａ、１１ｂは、第１と第２の発光ダイオード７ａ、７ｂに対応する部位でその屈折角を変えることにより、第１と第２の発光ダイオード７ａ、７ｂによる照射範囲は全体として円形にならず、縦長になるから、作業対象箇所の必要な範囲を、近い部位Ａも遠い部位Ｂも同時に照射することができる。このため、ビットやネジの長短などに合わせて発光ダイオードの照射角度をいちいち切り替える必要がない。したがって、取り扱いが簡単で、作業性も向上する。   According to the above configuration, the transparent cover portions 11a and 11b provided at the front portion of the light emitting diodes change the refraction angle at the portions corresponding to the first and second light emitting diodes 7a and 7b, so that the first Since the irradiation range by the second light emitting diodes 7a and 7b does not become circular as a whole and is vertically long, the necessary range of the work target portion can be simultaneously irradiated to the near portion A and the far portion B. For this reason, it is not necessary to switch the irradiation angle of a light emitting diode according to the length of a bit or a screw. Therefore, handling is easy and workability is improved.

また、上記左右２個の発光ダイオード７ａ、７ｂは同じ角度で設けられているから、その取り付けや組立作業が楽であり、取り付けスペースも小さくて済む。   Further, since the two left and right light emitting diodes 7a and 7b are provided at the same angle, the mounting and assembling work are easy, and the mounting space is small.

なお、第２の発光ダイオード７ｂに対応する部位のカバー部１１ｂの前端には、図１（ａ）（ｂ）及び図４（ｂ）に示されるように、第２の発光ダイオード７ｂから発光された照射光を絞るレンズ部１２を形成するのが好ましい。これによれば、近い作業部位Ａに対する照射角度をαとすると、遠い作業部位を照らす光は拡散せず、その照射角度βは、上記角度αよりも小さくなるので、必要な作業部位を明るく照射することができる。作業対象箇所の必要な範囲を、遠い作業部位Ｂも近い作業部位Ａも同時に明るく照射することができる。   In addition, light is emitted from the second light emitting diode 7b at the front end of the cover portion 11b corresponding to the second light emitting diode 7b, as shown in FIGS. 1 (a), 1 (b) and 4 (b). It is preferable to form the lens portion 12 for narrowing the irradiated light. According to this, when the irradiation angle with respect to the near work site A is α, the light that illuminates the far work site is not diffused, and the irradiation angle β is smaller than the angle α. can do. The necessary work area can be illuminated brightly at the same time in both the far work site B and the close work site A.

また、上述の形態とは逆に、第１と第２の発光ダイオードを、主に遠い作業部位を照射する角度で取りつけ、第１の発光ダイオードに対応するカバー部を偏肉にして近い作業部位を照らすように屈折角を変え、第２の発光ダイオード７ｂに対応する部位のカバー部にレンズ部を形成する構成にしてもよい。   Contrary to the above-described embodiment, the first and second light emitting diodes are mounted at an angle that mainly irradiates a distant working part, and the working part close to the first light emitting diode is made thicker. The refraction angle may be changed so as to illuminate the lens, and the lens portion may be formed on the cover portion of the portion corresponding to the second light emitting diode 7b.

さらに、第１の発光ダイオード７ａと第２の発光ダイオード７ｂは、同じ角度ではなく、それぞれ近い作業部位と遠い作業部位を照射する角度に設けられていてもよい。この場合も、透明カバー１１には、第２の発光ダイオード７ｂに対応する部位のカバー部の前端にレンズ部を形成して遠い作業部位を明るく照射するのがよい。   Furthermore, the first light-emitting diode 7a and the second light-emitting diode 7b may be provided not at the same angle but at an angle for irradiating a near working site and a far working site, respectively. Also in this case, it is preferable that the transparent cover 11 is formed with a lens part at the front end of the cover part corresponding to the second light emitting diode 7b to irradiate a far working part brightly.

さらにまた、図５に示されるように、照明ライトを２個の発光ダイオードでなく１個の発光ダイオード７ｃによって構成し、この発光ダイオード７ｃの前方に設けた透明カバー１１の一部１１ｂの屈折角を変えて近い作業部位と遠い作業部位を同時に照らすようにしてもよい。   Furthermore, as shown in FIG. 5, the illumination light is constituted by one light emitting diode 7c instead of two light emitting diodes, and the refraction angle of a part 11b of the transparent cover 11 provided in front of the light emitting diode 7c. It is also possible to illuminate a near work site and a far work site at the same time.

この場合も、上記透明カバー１１の遠い作業部位を同時に照らす方の部分には、上記発光ダイオード７ｃから発光された照射光を絞るレンズ部１２を形成するのが好ましい。   Also in this case, it is preferable to form a lens portion 12 for narrowing the irradiation light emitted from the light emitting diode 7c in the portion that simultaneously illuminates the distant working portion of the transparent cover 11.

上記構成によれば、１個の発光ダイオード７ｃでも照射範囲を縦長にして、作業対象箇所の必要な範囲を、遠い部位も近い部位も同時に明るく照射することができる。   According to the above configuration, even with one light-emitting diode 7c, the irradiation range can be made vertically long, and the necessary range of the work target location can be simultaneously illuminated brightly at both the far site and the near site.

また、透明カバー１１の遠い作業部位を同時に照らす方の部分には、上記発光手段から発光された照射光を絞るレンズ部１２ａを形成したから、遠い作業部位を照らす光は拡散せずに必要な作業部位を明るく照射することができる。   In addition, since the lens portion 12a for narrowing the irradiation light emitted from the light emitting means is formed on the portion of the transparent cover 11 that simultaneously illuminates the far working site, the light that illuminates the far working site is not diffused. The work site can be illuminated brightly.

なお、ライト付き電動工具はインパクトドライバに限定されない。電動ドリル、電動ドライバのような電動工具にも適用することができる。   The lighted power tool is not limited to the impact driver. It can also be applied to electric tools such as electric drills and electric drivers.
